Research on stiffness matching of support structure of high-precision equipment on satellite

This paper takes the support structure of high-precision equipment on satellites as the research object, and combining it with the characteristics of an actual satellite platform, analyses the stiffness matching between the platform and the load mounting point represented by the axial connecting relay. On this basis, the support structure of two different types of installation points is quantitatively evaluated, the optimal configuration is selected through the analysis result, and the design improvement measures are proposed. It provides a new design idea for the support structure of the same type of high-precision equipment on satellite.
